Abstract:This paper studies on the measurement techniques of radioactive inert gases
emited in nuclear power plants. Through illustrating the principles of generating
electricity, we know the radioactive inert gases sources and the radioactive hazards
on human primarily sensitive organ. Then, we introduces the principles of nuclear
radiation measurement, and the measurement methods, such as ionizing room messurement
method, plastic card bodymeasurenment method, semiconductor dector method,and make
some comparison as well. In this paper ,we put forward "online survey" cocept ,
correction the shortcomings of the traditional measurement methods.For example, the
need to read out the data with other equipmen resulting in the acquisition of outcome;
Most methods can only carry on a point measurements, and materials consistency is
poor;Except for the photosensitive film mthod,the other methods are poor at spatial
resolving power.The hardware and software design method in automatic cotroll field
are applied to the field of nuclear radiation measurement,to realize the design about
radioactive inert gases measure based on CAN bus.In the paper we make the choice from
sampling methods to measure mthod and point out the technical indicators we shoud
reach.
